I like that it allows me access from anywhere at anytime through my phone or computer as well as having multiple platforms for communication with clients which helps us keep track of what we need to do next! It does take some getting used too if you're not familiar but once your comfortable then there's nothing better than being able to work remotely without worrying about office politics etc.
The system can be confusing sometimes so its best just ask someone who knows how things are set up before doing anything yourself otherwise you may end up wasting time trying something out only realize later down the line when others have already done all this hardwork for you :).
